SI005 – Stock Update Speed

Overview

Assessment for stock update speed. Looks for indicators of real-time or fast inventory updates: real-time indicators, timestamps, change notifications, update frequency.

Probability that AI systems use this signal: Crawlers and generative AI pipelines consume structured and visible page signals for training and inference. Assessment-specific signals (e.g. schema, canonicals, trust cues) affect how likely a page is indexed and surfaced. The probability that this assessment's signal influences AI behavior is high when the page is in a product or compliance context.

Impact on geo compliance: Passing this assessment supports geo compliance by ensuring machine-readable and visible content meet standards that reduce the risk of wrong locale, pricing, or trust in AI-generated answers. Failing can lead to non-compliant or misleading surfacing.

What We Check

  • **_extract_stock_information:** DOM/classes or data attributes for real_time_indicators, update_timestamps, change_notifications, update_frequency (implementation uses regex/class patterns).
  • **Scoring:** real_time +40, update_timestamps +30, change_notifications +20, update_frequency +10. Max 100. **PASSED** if score >= 60.

Pass / Fail and Score

  • **PASSED** if score >= 60. Score: real_time_indicators +40, update_timestamps +30, change_notifications +20, update_frequency +10. Max 100.

How to Fix When It Fails

  • Implement real-time stock status updates; add timestamps; implement stock change notifications; add update frequency info.

Common Issues

  • No real-time or timestamp/notification/frequency indicators in page.

Dependencies

None.

How to Verify

  • Check DOM/classes or data attributes for real-time indicators, timestamps, change notifications, and update frequency.

Additional Resources

  • Real-time or fast inventory signals: DOM/classes or data attributes for timestamps, change notifications, update frequency. Align with SD010 (inventory sync) and SD006 (dynamic data stability).
  • schema.org Product / Offer: use availability (e.g. InStock, OutOfStock) and optional availabilityStarts/availabilityEnds for time-bound availability.
